mileage improving?
I am just under 5k miles on my 08, F350, 6.4, 3.73, auto, reg cab. Brand new I was getting 11-11.5 mpg max in the "city". Now I am at 12-12.5 in the "city". This is hand calculated and filling the tank to the exact same level (up to the cap) each time. BTW the computer is pretty accurate. It's usually within .5mpg. Anyone else notice an improvement?

11.5 is what i get with my dually and 4.10 gears.....with alot of short trips, stop and go...5600 miles now, and yes, the warmer temps make a huge diff, I saw 13+ on a 100 trip when it was 65 degrees...never saw 13+ until now.

My truck is a 350 crew cab long bed srw I have 12500 miles I get an average of about 13mpgs this is mixed city and highway driving with 4000lbs in my trailer.I pull my trailer only a couple of days a week This is hand calculated by the tank.I used to only get 10 mpgs It definately rises slowly so have hope.I always use 16ozs of usld deisel klean cetane booster I'm hoping to extend engine life by using this but I definately notice a performance change as an added bonus Oh yea I forgot to say I love this truck.Upgrades coming when I can afford them.I definatley think these trucks can handle a little extra power, they don't have to work to hard the way there tuned.
